1 Claim.

As the title of the invention implies, the device hereinafterspecifically described has reference to an improved type of terminalclip such as is adapted for connection with the post of a conventionalstorage battery.

Needless to say, we are aware of the fact that the art to which theinvention pertains is characterized by innumerable types and forms of'socalled terminals of the clamp and clip form. Notwithstanding thishighly developed state of the art, we have evolved and produced a novelcontribution which, it is believed, possesses features which transcendthose exemplified in marketed and patented terminals.

It follows, therefore, that our primary aim is to generally improve uponprior art devices known to us by providing a simple and economicalsectional terminal of a two-part clasp type susceptible of expeditiousapplication and removal, and not likely to become anchored on the postby adhesion caused by corrosion.

The specific adaptation and coordination of features will become morereadily apparent from the following description and the accompanyingillustrative drawing.

In the drawing:

Figure 1 is a view partly in section and partly in elevation showing aterminal clamp constructed in accordance with the principles of thepresent invention.

Figure 2 is a side elevational view observing the details illustrated inFigure l in a direction irom left to right.

Figure 3 is an elevational view of the opposite or diametrically opposedside of the clamp, that is, observing it in a direction from right toleft in Figure l. a y

In the drawing, in Figure l, the conventional storage battery is denotedby the numeral :3 and the tapered post is indicated at 5. These areconventional parts. The sectional or two-part terminal clamp isindicated by the numeral 6. This may be said to be made of a pair ofcompanion or complemental clip units l and 8, respectively. These areformed from metal of appropriate proportions and are substantially alikein construction. The lower end portions are of arcuate or semi-circularform as indicated at 9 to form jaws which efieetively grasp and embracethe post. The jaws are shaped to conform to the contour of the post. Theintermediate portions of the units are profided with overlapped lugs orcars ill pivotally' connected together in hinged relationship asindicated at H. The upper end portion is of the unit or section? isformed with a reinforcedv screw-threaded? hole forming a. nut iii toaccommodate the screwthreaded stem it! oi the fastening or binding setscrew. The outer end of the set screw is formed with a finger piece I!to facilitate actuation. The inner end is rounded somewhat to provide athrust element I! which is seatable in a socket formed in the thickenedupper end portion ll of the unit 8. It follows therefore that the jaws 9are simply slipped down over the post and the set screw is tightenedYDIOI'OG the jaws into efiective binding contact with the post. This setscrew arrangement and thrust action is an important factordistinguishing the invention.

We call attention now-to the adapter clip l8 which is constructed andformed as an integral part of the unit 8 to accommodate the cable orconductor line (notshown). In addition, as an' important feature, wecall attention to the numeral l9 which indicates a. stop element, thisbeing integral with the law on the part 1 and located at 'right anglesthereto so as to overlie the end of the post. This limits the downwardplacement or positioning of the clamp 6 as a whole. In addition to this,it serves, when the parts I2 and I! are pressed together with a tool, tobear down against the post and to break the corrosion bond, if any, andto aid in loosening the clamp it it has a tendency to adhere to thepost. Thatis to say, as the parts I and 8 are pressed together at theirupper ends with a tool, this tends to cant the stop element l9 againstthe post producing a thrust action which is helpful in releasing theclamp from the post.

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considerlng the description in connection with the drawing.Therefore. a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangeping ears on intermediateportions of the jaws pivoted together to form a hinge, a screw thread=ably mounted in one jaw and adapted to bean on the other Jaw todetachably lock the jaws in closed position on the post oi a battery, alaterally projecting conductor sleeve on one jaw, a

horizontal bridge wall formed on the other jaw below the hinge andextending across the major portion or the space between the jaws wherebya fulcrum is provided for canting the jaws free from a corroded pest andat the same time prevent corrosion from efiecting the hinge.
